I'm running a Asus Sabretooth p67 motherboard with the latest BIOS @3602. After installing my KFA2 Geforce 1080, it'll freeze on the BIOS screen and boot won't progress. Keyboard is also unresponsive.
After some tinkering with it, I noticed in the changelog for BIOS 3602
"4. Fixed Nvidia GTX 680 hang when runing with UEFI driver."
Thinking the 1080 might be affected by this bug, entering the BIOS and changing "PCI ROM Priority" to "Legacy ROM" fixes this issue.
Note that changing this while using the RAID functionality might cause your machine to become un-bootable until you revert the setting back. I hear the EFI RAID ROM uses different drivers. You might need to reinstall the OS.

So it sounds like newer graphics cards these days have both an EFI and "Legacy" ROM on them. Only difference noticed so far is that I don't get a higher resolution on the POST screen. My 580 didn't have an EFI ROM.
Hope this helps someone out there.
